Abstract
Effect of Increased Maximum, Minimum Temperatures and Chorbondioxde on Chickpea (Cicer Arietinum L.) Yield and Yield Parameters: A DSSAT Chickpea Simulation Study
The probable effect of Start of irrigations in Harran Plain, effect of global warming, and development in both city and the industry on daily maximum and minimum temperatures and CO2 increase effect on chickpea was evaluated using DSSAT (Decision Support System for Agrotechnology Transfer) simulation model. Maximum and minimum temperatures were increased with 0, 2, 4, and 6 0C while CO2 was increased with 20 ppm increment from 380 to 440 ppm. Simulation results indicated that the effect of increased minimum temperature and CO2 were limited on yield, biomass, and crop water use (ETc). However, increase in maximum temperatures was noticeable and increased yield and biomass about 35% and ETc about 10%. When new agricultural land open to irrigations, probably the calculated amount of water for the area will not be enough and needs to be increased according to increase in ETc.
